To all whom it may concern.-

Be it known that we, Jnssn D. Bacon and THOMAS MCGARRIGA citizens of the United States, residing at Paducah, in the county of hicCracken and State of Kentucky, have invented certain new and useful improvements in Fireplace-Heaters, of which the following is a specification.

This invention embodies a system of heating particularly adapted for dwelling-houses, the object in view being to provide a comparatively simple arrangement of warm-airconducting fines in conjunction with a fireplace-heater, the latter being of a special construction similar to those at present in general use.

Ourinvention relates to that class of heaters in which cold air is primarily heated, after which the same is passed into a hot-air chamber and flue, being distributed from the latter to the various rooms or parts of the dwelling which are to be heated.

An important feature of our invention re sides in the fact that pure air is constantly distributed, so that thorough ventilation is always had, and it is contemplated to provide means for imparting a certain degree of moisture to the air to overcome unhealthy dryness of the same when necessary.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a vertical section showing a fireplace-heater constructed in accordance with our invention. Fig. 2 is a broken horizontal sectional view through the fireplace. Fig. 3 is a vertical sectionalview bringing out more clearly the arrangement of the hot-air and smoke lines and the inlet and outlet iiucs extending from the hot-air flue. Fig. 4 is adetail perspective view of the jacket or shell which extends in rear of and at the sides of the fireplace. Fig. is adetail viewembodying a modified construction of shell and drum carried thereby.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the saint: reference characters.

in the drawings the invention is shown in its application to an ordinary fireplace 1, within which is l cated a grate 9,. The fireplace is shown located in an ordinary room. and it will be understood that any heater of analo gous type may be employed in accordance with our invention so far as the operative principles thereof are concerned. A jacket or shell 3 extends in rear of and at the sides of the fireplace l, and this shell is of a peculiar form specially adapted for use incarrying out the objects of our invention. The jacket or shell 8 comprises a rear somewhat inclined wall 3,side walls 3",and an upper horizontally-disposed cover 3. in rear of tee shell 3 and partly formed thereby is located a hotair space or chamber from which extends a hot-air fine 5. It is preferred that the fine 5 er;- tend the entire height of the building within which the invention is being employed and that warm-air flues lead from this hot-air flue 5 into the various rooms adjoining and distant therefrom, as the same may be. From the cover-wall 3 of the shell 3 extends the smoke-flue 6, which latter is to be connected at its lower end with the wall 3 by any suitable means. The wall 3 is provided with an opening 7, through which the smoke and prod ucts of combustion pass to the smoke-flue 6. Projected from the rear wall 3" of the shell is a hollow extension 8, which may be described as of angular or L form in cross-section, and beneath the extension 8 aforesaid is located a heating-drum 9. The heating-drum. 9 is of tubular form and is transversely disposed with respect to the fireplace, having its ends passed through the side walls 3" of the shell 3. so as to admit in the preferred construction of the invention of the passage therethrough of cold air. The heating-drum a is connected with fresh-air-supply pipes 10, said a he pipes 10 being; connected with thrends of the drum and passing through the rem-r well 3" ol the shell The lreslruin-supply pipes 'l 0 may lead from any point outside o'l the building s' as to continuously supply the pure :iiiz which is heated previous to distribution tl roughout the building. The ends of the drum 9 nre preferably threaded into rmeningggs in the side walls 3" of the shell El und it will be noted that the drum is disposed in the :u'igle torn] ed at the point of juncture of the lower portion of the extension 8 with the r well 3 of the shell. The drum beceuse of its location thus receives 1r maximum amount of he so :is to quickly hen; the fresh air passing thereinto from the coinn'iunicetino supplypipes 10. 'lle supply-pipes inc connected. with the drum 9 at the ends of the letter, and the air passing into the drum is coiulucted therefrom through ninpipes fl and fl, the pipe 9 extending through the lower well of the extersiei 8 wheiius the pipe 9 iusses "lireug'h the rem well 3 of the shell llzjth pipes 9 and 9" lead into the worm-air s nce 4;. Des-scribing more clearly the udrzuitnn'es of the location of the drum, it may be said that the lower well of the extension 8 coniprisesz, deflector to confine the heat in that portion oi'' the shell within which the drum is located, the smoke our products of combustion, howeven, being adopted to puss above the extension l into the smoke-line 6 in a manner which will be readily seen.

(:hu'roumling' the smoke-flue G and between the smoke-flue and the lls of the warm or hot air line 5 end :it points in the length of the sinohe-l'lue ltI'G disposed n pl urulity of diaphragms ll, which later conline the bent in certain portions ol the hot-eir line in n menner which will be more clearly described. The dinphrnn'ins's ll rigidly reinforce "the smoke/dine to support the in ne within the L hot-air line 5, find to ell'ord n'i'enter rigidity of the Llllll3lll'itgll'l8 some are nni'iulnrly depressed or col-rug ns shown nt 11. lhe diuphrsgnas 11 may be provided with dampers '1'" pivoted thereto, as shown niost clesrly in i 1g. 1i and the said dampers 12 are operated by menus ol lnindles 13, c nveniently locnted lo r o perziti on.

The lnindles l ol the dampers are connected with bell-crnnl; levers 'l at corres mndinef ends of said levers, end connectrug-burs in directly connect the opposite ends of the bell-crank ll1-."lf:% with the dampers. perzition of the dampers to open some will admit of direct puss-cure of wnrni air from the lietnirspecel up the worm-sir lluc 5 as found necessnry. Secured to the dir phreg'ins ll are u phiirnlit of supper-tine members it in the form ol hooks, and these [rocks are utilised to support wuter-recepumles should it he desired to impart moisture to the dry ltik wnich men'ibers 16, however, may be utilized for rious nirposes, since they are located in 21 hot air space end zirticles cl food might be rendily and quickly wormed by suspension of the cooking; vessels from the members 16 in a manner which will be readily comprehende 'lhc pre'li'erred numner of distributi \Vltl'll) air from the hot-air space consists in the provision o'l ulcts 17, which lend from the wzirnrnir space 5 u t at point near the lower portion of the rooms, and the said inlets may be closed by registers or any suitable means for governing the supply of warm air. The wu'in air after passing into the rooms ucnpted to pass from the rooms through outlets 18, located near the ceilingef each of said rooms, and this warm air in passing off is again received in the wermmir flue 5, being; mixed with any warm air which may already be located in this line. 'lheinlets and outlets l? and 18 nmy also be provided with governing-registers of any suitable type found preicrable and suitable for the purpose of our ve ition. it will be noted by reference to iii 1 and that the outlet opening's through which. the u'erni air posses into the rooms are of such n size to rezidily admit of disposal of any recep les or vessels upon the supportiiuy members in whever this is found desirable in accordance with the Lill'pQSeS nbove described, The out let and iiilet means provided in connection with our u nrni-nir line may lea lllllBrGli'Olll in any oirect on found n ccssnxy order to properly convey the nir to its desti lotion, and the we. In-1th three easy l e connected by pip-es to rooms sittnted at u distance thetroni.

ln the :nodilicntion shown in 5 our hosting-drum is utilized to contain \Vlltfil to bent some for distubution through pipes under the low or high pressure SyStfilllS, and when thus used the ends of the some may be closed by cups 0' suitable means and a pine or 'iipes 19 led from the snid drum upwurdl through the extension 8, tossing to any 3) i of the building which it may be desired to heat. A second water-supply pipe 20 is i in the modl ied invention above mentioned, and this pi pc is connected with my convenient reservoirs or source oi supply. The pipe .20 would preferably pass through the well 3 cf the shell and is coupled to the drum or reservoir 9 at the point at which the sir-pipe ll" is ordinnrily uttnched when drum 9 is used for air-heating purposes.

it will be noted that th s r-pipes Wand 9", which lead from u point chant intern'iedintc the ends ol? the drum 9., so as to condu at tlu. heated air into the hot-air space, are so rnnn'ed thnt the craft througni the pipe 9 greatly increases the drzrlt through the pipe 9, since the hot air in passing into the hotnir 8132108 through the pipe ll" nrst pass l wnrdly udjucent the point at which the pine Sllcnds into the extension 8. Also it will be reams a;

readily seen that a maximum amount of cold air is admitted into the drum because of the location of the inlet-pipes 10.

Having thus described the invention, What is claimed as new isin a fireplace, the combination of a lireplace, a jacket or shell consisting of a rear wall, side Walls and an uppermost horizontal cover-wall, a hot-air space adjacent the shell, a hot-air flue leading" from the hot-air space, the upper Wall of the shell being provided With a smoke-outlet opening, a smoke-flue leading from said opening of the shell, a hollow extension projected from the rear wall of the shell adjacent the upper portion thereof and extending above the comhustion-chamber of the fireplace, a drum beneath the hollow extension aforesaid and having its ends leading through the side walls of the shell, coldair-supply pipes leading into the ends of the drum aforesaid, and outlet air-pipes leadingfrom the drum to the hot-air space, one of said outlet-pipes leading into the hollow extension and the other through the Wall of the shell.

In testimony whereof We afiix our signatures in presence of two Witnesses.
